i have done some research on building a home audio system out of car audio equipment, and i know its not recommended, but wanted to see what it would take. I would like to keep it simple, 2 speakers with tweeters and a subwoofer. Most receivers take and independence of 8 ohms and car speakers run on 4 ohms but i found Onkyo receivers can deal with 4-8 ohms independence and the receiver would put out around 125 W/Ch. When it comes to the car audio i want to go with Rockford Fosgate speakers so i was thinking about the P1675-S speakers but i dont know if they would need crossovers or not, i dont really know much about them. I know that the subwoofer would have to be about the same size as the 6.5 speakers and run at 4 ohms but im not positve. Im mostly concerned on how much power the whole setup would draw and if it was even possible.
Any advice would be very helpful thank you!!!!

Hi Chris,
I'm not an expert but here is what I can tell you:
Rockford produces quality speakers, so that's good choice. They say that one pair of p1675-s includes integrated crossovers. I'm not really sure what that means, is it only cap for tweeter or is it "real" crossover for both speakers. Generally my opinion is that you wouldn't need additional crossover for them.
About receiver, most receivers today can run 4 and 8 ohm speakers with no problem, even older ones. I had NAD from 1970. and I made it run 2 ohm 200W subs.
About subwoofer, 6,5" is really small for that. I wouldn't even think about sub smaller than 8" or 10". Also, are you planing doing 2.1 setup (2 speakers, one sub), or is it 2 subs, one sub in box with one P1675-S, making it one pair of full range speakers.
Lastly power, P1675-S are 60W RMS speakers, with them, I would use at least 150W subwoofer, that's total of 310W. But it depends on what are you going to do with these speakers. I have 3 pairs of home made speakers, each 120W, 2 car subwoofers both 500W, all RMS, but I daily use below 1W per speaker for listening music. All that power is for party or movies.
I hope this helped.

this helps immensely!!!! I was planning on 2 small boxes for the P1675-S, with 1 sub box. well lets say i go with at least the 150W sub plus the 2 P1675-S thats 270W RMS isnt it? what are you using to power all of those speaker and subs? cuz your looking at around 1360W. How do you know how many watts are coming out of the receiver? idk if im doing this right?
Yes, that's 270W RMS, I calculated it wrong. But, it all depends on what are you using them for. Most of the time you will not need half of that power, on maybe you will always turn them all the way up. My speakers were powered by old NAD amplifiers, 200W per channel, but since they burned in house fire I am powering my new speakers with home made amplifiers, one amp per speaker. Each amplifier has about 150W RMS. Subs are also powered by home made amplifiers, but each 600W RMS.
I know speakers have 120W, because that's what it's written on them, and about amps, well this one is for my speakers http://www.diyaudio.com/forums/chip-amps/206591-tda7294-power-transistors-amp-tda7293-come-also.html and ones used for subs are made by friend and can easily max out subs rated at 750W.
So, I'm not using receiver, but one better receiver can be used for main and surround speakers, but subs demand too much power for anything "normal". I like to have a bit extra power in my amps, but it's not necessary, as I said before, I usually listen at lower than 1W per speaker which produces 86-90 dB.

so my final question is can i hook up all 3, the 2 speakers and the sub, to a receiver thats putting out around 160W/ch at 4 ohms
It's hard to say. How many channels do you have?
If it's each speaker on it's own channel it's ok. Tell me your setup and I'll tell you if it's ok or not. Or if you don't have receiver yet, I can tell you some examples with different types/channels etc.

Hi,
I'll give you a simple answer, forget it, you cannot build good
home hifi out of car speakers that work well on the cheap.
You can use car speakers if you really know what you are
doing, but unsurprisingly if you do know what you are doing
home hifi drivers are nearly always a better choice.
It gets blurred with subwoofers TBH.
Main speakers you could do a lot worse than these :
X-LS Classic kit and better for a lot more money.
